Abstract
Fifty-seven samples from nineteen locations extending along 800 kilometers on
the southern Mediterranean shore between Bsees town and east of Zuwaitinah
harbour, were examined for their organic contents. Sampling was conducted
under the following specifications:
1. Dry beach sand, 3 to 4 meters away from water (denoted ds).
2. Wet beach sand, obtained from 1 meter depth (denoted ws).
3. Beach water (denoted w).
Known amounts of sand (ds or ws) and beach water (w) were extracted with
chloroform. Organics in the extracts were determined gravimetrically and were
examined by gas chromatography. Alternatively a direct determination of
organics concentration in CHCls solution was obtained spectrophotometricaily
from calibration curves of absorpti
